Here is our standard wiring harness: How to Wire your LED Light Bar With a Relay Switch. I left the relay out completely, that does nothing but kill one of my hi beams. FYI: … But don't these heavy duty relays use a lot of power to keep them energised comparaed to a much smaller "cube" type relay. However, there is an important difference in the construction of a motion detector. i would imagine a 5w LED would be fine without a relay.Connect them up without a relay… When wiring a house, it's always a good idea to put lights and outlets on separate circuits, which guarantees that if the outlet circuit fails, you still have light. Under the hood I swapped the horn relay with the ECU relay and it fixed the problem. It stops the brake lights from functioning until the vehicle is started. Bought and installed a wiring harness and now they won’t work at all. the other reason to use a relay is so you don't burn out your ignition switch. You can Get the Lights used in my Project here http://amzn.to/2xbRqr0 Today we are working on wiring some led lights to the switch box. : For anyone who has added LED bulbs to their vehicles turn signals or brake lights. This basically leaves you with a standard 12v power supply. Power door locks that do not function are another common symptom for a problem with the door lock relay. A basic relay circuit you can use for devices such as fog lights, electric compressors, c.b. Those relays are side by side and they're all the same. It can be found in the bottom left-hand corner of the Relay Box as shown in the image below: The symbol indicates that the relay is the R4H810A, used with the T6 wired smart thermostat. The fog light relay is the switch that controls power to the fog lights, and it is usually controlled either automatically by the computer or manually by the driver. I understand the usual way to do this is to use a relay so that when a switch is turned on then the relay alows power to the lights. Relays and contactors allow for remote switching of loads and to switch higher voltages and currents than a small switch will safely control. Double and triple checked all connections, reversed polarity, but still nothing. I'm … If there's a short, the fuse is … if you start adding fuel pumps, electric fans, amps and all that other stuff, it is possible to burn up the contacts. In this case, the switch the OP wants to install has a max capacity of 30 amps, which is 10 times the 3 amp draw of his lights, so no relay is needed. Motorcycles are notorious for having weak electrical systems and switchgear that hasn’t really kept up with the demand for high output headlight bulbs, heated vests and gloves and … A relay uses a tiny bit of power from the headlight switch on your dashboard to "flip" another, bigger switch, which turns the headlights on.

Thinking out of the box for example only, now picture a sports field with flood lights and it is time to turn on the lights. The lighter instrument panel switch and wires control the relay, which in turn controls the heavy current to the lights. As long as you don't put too many lights on the light circuit, you can usually control that circuit with a 15-amp breaker, as well as wire it with a 14-gauge wire. When switch is in "ON" position, current flows to relay which switches "ON" high current to your device. It all depends on the current and Wattage of lights, the thickness of the wire and capacity of the switch. NOTE! This allows LED lights to function properly, without flashing, at a the fraction of the cost of a dedicated plug-in kit. Since the LED bulbs use less Amps than normal bulbs, the flasher unit thinks there is a bulb burnt out and doubles the flash rate. The 10A Tail relay is probably the one you blew, since your trailer lights are probably plugged into the same circuit as your trucks lights.
